The growing interest in the open access of groundmotion data, webservices, and tools motivate every year a new release of the ITalian ACcelerometric Archive (ITACA), which represents the most complete collection of accelerometric waveforms recorded in Italy. In the last years, ITACA has undergone an important renewal process resulting in a new layout of the website (http://itaca.mi.ingv.it) and substantial changes in the database content and services. In this work we present the main feature of the last release of ITACA v3.1 (last accessed on July 2020), providing Users with information to browse the website and to access and analyze data.
